The study of strata is called stratigraphy. Stratigraphy can be used to determine an approximate age of fossils in rocks.
Sedimentary rocks, such as limestone, sandstone, and shale, are the most common types of rocks that contain fossils. Fossils are formed when the remains of plants and animals are buried in sediment and eventually become preserved in rock over time. Igneous and metamorphic rocks typically do not contain fossils.
Sedimentary rocks form three horizontal layers: strata, singular and stratum. The organisms that fall into the sedimentary rocks, will then be fossilized in each layer.
Igneous rocks are formed from cooling and solidifying of molten rock, so they usually do not contain fossils. This is because fossils are typically found in sedimentary rocks, which form from the accumulation of sediment and organic materials, preserving the remains of plants and animals.
Fossils found in the lowest geological strata are generally more primitive than those found in higher strata. This principle is known as the Law of Superposition, which states that older rocks are found below younger rocks in undisturbed layers, reflecting the progression of life forms over time.

Radiometric dating of fossils is not possible beyond roughly 70,000 years. However, when fossils are found in association with strata of volcanic and metamorphic rocks which can be dated radiometrically, a very accurate age of the fossils can be determined.

== == Sedimentary rocks may exhibit strata, or layering. Sandstones will have visible sand grains. Limestones will fizz when placed in vinegar. Fossils usually only appear in sedimentary rocks. A rock made of an assortment of other rocks is usually sedimentary.
Because most fossils are found in rock strata, the method for dating them is the same--measuring the amount of decay of an isotope.
Sedimentary rocks have layers or strata, often with visible grains or fossils. They can be distinguished from other types of rocks by their layered appearance and the presence of sedimentary structures like ripple marks or cross-bedding.
because they are rocks and fossils dont belong in rocks and fossils can be made things an rocks cant :(...
